Patented Apr. 12, 1932 UNITED stares PATENT* OFFICE FRANK C. HINCKLEY, FSTRATFORD, CONNECTICUT, ASSIGNOR TO COLUMBIA PHONO- i GRAPH COMPANY,TNC., OF BRIDGEPORT, CONNECTICUT, A CORPORATION OF NEW` YORK PHONOGRAPHApplication led September 26, 1930. Serial No. @4,4824

y V This invention relates to new and useful improvements in phonographsor talking machines and has particular relation to socalled portablephonographs, being an improvement on the structure shown in my UnitedStates Patentf1,776,905 of September 30th, 1930. i

An object of the invention is to p-rovide a phonograph which while smalland compact and therefore particularly adapted for use as a portable orStowaway phonograph yet is so constructed as to give large volume, itsvolume and tonal quality corresponding favorably with the volume andtonal quality of floor type phonographs. l

Another object is to provide a phonograph including animproved soundamplifying arrangement, the invention particularly relating to the bellor lmouthY portion of the amplifying system of anacoustic phonograph.

A further object is to provide a portable phonograph including a coverwith which side wings co-operate when the cover is openwhereby toprovide an extension for the horn or amplifier of the phonograph, aportionof said side wings being foldablewhereby when the machine isVclosed as for transportation a compact and relatively small structure ishad.

An additional Objectis to'provide a phono-y graph having characteristicsstatedr and wherein a record carrier ory other means within the lid orcoveris so constructed that it divides the "bell or mouth portion of theamplifier which bell or mouth portion is formed by the cover ,and sidewings inassociation with the body of the machine. kOther-objects andadvantages will becom apparent from a consideration ofthe vfollowingdescription taken in connection withy the accompanying drawingswhereinasatisfactory embodiment of the invention is shown. However, itisv to be understood that the invention is'not limited to the detailsdisclosed since changes in the construction, combination and arrangementof parts will readily suggest themselves to' thosek skilled in the art.Since the invention comprehends all such variations and modifications asfall d within the scope of the appended claims, reference must be madeto the annexed claims Figure l is a central longitudinal sectional viewthrough the entire machine, the lid or cover being open, and the recordcarrying panel and khorn dividingmeans beinginy its lowered position; cv

Fig. 2 is a plan view of the cabinet or body of the machine, the coveror lid being removed andthe foldable portions` of the side wings beingin folded position; n

Fig. 3 is a view looking from the right in lig. 2, the cover being inplace and closed, a side wall ofthe body and cover being removed,` andthe record supporting panel being shown in section; Y

Fig. 4 is a perspective view ofthe bell Vor mrith portion arrangement ofthe amplier; an A Fig. 5 is an enlarged sectional detail view showingthe mounting for the lid orcover and the record carrying panel or horndividing means. l

Referring in `detail tothe drawings,at 6 is shown the cabinet or body ofthe machine to one edge of which, preferably the rear edge, there ishingedly secured a lid or` cover 7 Within the cabinet or body 6 thereisdis# posed 'a partitionvor'motor board 8 secured inv any suitable manneras for example by having its edges set into the ,Walls ofa cabinetorbody asshownat9.vk f

The motor-boardor partition 8 is disposed relatively nearto the upperedge of the body 6 and a compartment 10V is formed beneath the motorboard or between the motor board and the bottom 1l of the cabinet orbody. At its rear edge the partition 8 is cut away as at 12 to form anexit for an amplifier 13 disposed within the compartment 10. Theamplilier 13 willlater be more fully described..V

At itsunder side the partition 8 supportsy any suitable motor. indicatedat 14 which through avertical spindle 15 extending upwardlyl through thepartition, drives a turntable 16. Obviously, the turntable is for the 14may be employed and that any type of turntable 16 may be employed, theparticular type of motor or turntable having no relation to the presentinvention.

Through the forward end portion of the partition 8, or through that endor edge portion opposite the end or edge portion which is cut away as12, the partition is provided with a sound entrance opening 18. A tonearm 19 carrying a reproducer 20 for cooperation with a record on theturntable 16, is secured to the partition 8 in a position to align itsdischarge end with the entrance opening 18 through thepartition 8.

It is to be noted that the entrance opening 18 is located in one cornerportion of the partition 8. Secured to the underside of the partition ina position to receive sound through the opening 18 is the entranceportion of the horn or amplifier 13 which entrance portion may take theform of a casting 21 curving laterally of the cabinet as it curvesdownwardly and secured as by a flange 22 to the rear or small end of ahorn or megaphone 23 which is preferably of metal, as for example tin.

This horn 23 as shown is substantially Vrectangular in cross section andcomprises top, bottom and side walls and the casting may be secured tothe horn as by bolts 24. As herein disclosed the amplifier 13 issubstantially the same as that disclosed in my patent above referred toand extends across the cabinet and then rearwardly therein, increasingin cross sectional 'area as it progresses from front to rear, and at itsrear or discharge end being substantially the width of the cabinet. Theside walls 25 and 26 of the horn portion 23 abut against the rear wallof the cabinet as does its bottom wall 27. These three walls are held inposition and against rattle by meansof a block 28 having a curvedsurface 29 for the purposeof directing the sound upwardly through thecutout portion 12 of the partition. Top vwall 30 of the horn extends toa point substantially flush with the edge `of the cutout portion 12 andthe rear edge portion of said wall 30 is rigidly secured to thepartition as by means of a strap 31.

Lid 7 is connected to the cabinet 6 as by means of a hinge 32 and thelid has secured to it a pair of side members or wings 33 preferably ofmetal. These members or wings 33 are adapted to move into slots 34 inthe cabinet when the lid is moved to closed position and when the lid isin open position these members 33 close the corners at the connectionbetween the cover or lid and the cabinet or body. In this manner anextension of the amplifier 13 is provided since the lid, side wings andpartition 8 cooperate to provide a bell or mouth portion for theamplifier.

Mounted within the lid and movable about the same axis as that aboutwhich the'lid moves, is a record carrier or panel 35. This panel 35 ishingedly mounted through the medium of a bracket 36 bolted or otherwisesecured to certain of the leaves of the hinge 32 as at 37. curved on itsrear side as at 39 and co-operating with the upper edge or lip portion40 of a metallic strip 41. This is probably best shown in Fig. 5 and thestrips 38 and 41 cooperate to provide an unbroken surface at the hingedconnection between the lid and record carrying member and the body.

The panel 35 is movable to a position within the cover 7 where it may betemporarily held by means of a catch 42 co-operating with a catch plate43. Links 44 pivoted within the lid as at 45 and slotted as at 46 toreceive pins 47 on the edges of the panel operate to limit the swingingmovement of the panel outwardly of the lid. A cover 48 is hinged to thepanelV as at 49 whereby record compartment 50 is provided, records 51being shown in the compartment in Fig. 5.

The'V record compartment 50 begins at a point spaced from the rear orlower edge of the panel 35 and between its lower edge and the inner endoi the record compartment, the panel 35 has an opening 52 through it,the opening being preferably lined with metal as at 52a. This openingprovides a passage whereby sound passing upwardly through the cut-out 12in the partition 8 is divided, a portion of the sound passing upforwardly of the panel 35 and the remainder of the sound passing throughthe opening 52 and up between the cover 48 of the record compartment andthe inner side of the cover 7.

Hinged as at 53 to the side walls of the cabinet 6, are ak pair offoldable wings or members 54 and 55. These members, when open or inextended positions, are so disposed with relation to the side wings 33as to overlap the forward edges of rsuch wings 1 and further the members54 and 55 extend upwardly and at their upper or free edges bear againstthe inner surface of the side rails or edges of the lid 7 as shown at56.V

`Members or wings 54 and 55 may be temporarily secured in their extendedpositions by means of suitable catch members 57 However, this catchmeans or members 57 need only be used vfor holding the wings 54 and 55in their extended positions when the record carrying panel 35 is withinthe lid and secured by the catch 42. At other times, that is when thepanel 35 is in open position it is disposed between the foldable sidewings 54 and as shown in Figs. 1 and 4 and will hold them intheirextended positions.

It is, of course, only when the panel 35 is in its open or extendedposition as shown in Figs. 1 and 4 that a divided bell or mouth portionis provided for the amplifier. lVith Panel 35 carries a. strip 38 Qtinuation,

.the panel in its closed position, that is, with the panel within thelid and secured by the catch 42 but one large bellor mouth is providedfor the amplifier, that bell or mouth `being forwardly of the panel: 35.However, this bell or mouth portion will be considerably `larger thanthat heretofore provided. Also,.when the panel is in open position thedouble or divided bell or mouth portion Lis obtained. f

. Whenthe machine Vis to be folded as for transportation, it is butnecessary to release the members or wings 54 or 55 from the catches 57,to move the panel to a position within the lid and tothen fold thewings 54 and 55:.one upon the other as shown inFig. 2. Thelid or cover 7vmay then be lowered to the positionshown iny Fig. 3,-the-lid having-been secured in open position by means of a catch member 58cto-operating with one of they wings 33. V

v Catches 59 may be used for securing the lid o r cover in closedposition and may be provided with a carrying handle 60. Further, theexterior of the cabinet and the lid is preferably coveredy as withleather or imitation leatheras shown at 61. The wings or members 54 and55 are preferably of metal, as for example brass, and to. prevent theseparts from unnecessarily vibrating and also to have them so color ofthecovering material 6l, .these wings are ,preferablyI covered on their,inner and.

outer` surfaces with such material designated 62 which may be glued orcemented or otherwise secured to them. s
